Information on Result #625545
Linear OA(4120, 126, F4, 87) (dual of [126, 6, 88]-code), using repeating each code word 2 times based on linear OA(457, 63, F4, 43) (dual of [63, 6, 44]-code), using
- contraction [i] based on linear OA(4183, 189, F4, 131) (dual of [189, 6, 132]-code), using the expurgated narrow-sense BCH-code C(I) with length 189 | 49−1, defining interval I = [0,128], and minimum distance d ≥ |{−2,−1,…,128}|+1 = 132 (BCH-bound) [i]
Mode: Constructive and linear.
